m0useanswered grow question 10 months ago you can delete weeks in your diary and edit them. So you could remove all your weeks if you want or just some.
You can't have more then 1 of any given week number. eg week 2 is one and only. not week 2, week 2, week 3.
As far as I know you can not edit germination week to be week 1, once its set as germination its locked in unless you remove it.
You can however skip week 1 if you classify germination as week 1 but selecting the week as 2 when adding it into the diary.
Play aorund with the site and test it out. you can also make a fake diary to do this and them delete it after.
Good Luck!
